Dacre perhaps somehow tried to take in head of OFCOM (6)
I believe the answer is:
editor
'dacre' is the definition.
I can't tell whether this definition defines the answer.
'somehow tried to take in head of ofcom' is the wordplay.
'somehow' indicates an anagram.
'to take in' is an insertion indicator.
'head of' suggests taking the first letters.
The initial letter of 'ofcom' is 'o'.
'tried' with letters rearranged gives 'editr'.
'editr' placed around 'o' is 'EDITOR'.
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for editor that I've seen before include "Do tire out the newspaper head" , "One is in charge of publication" , "Person who determines the final content of a text" , "Wapping boss" , "Newspaper boss" .)
